Abstract:
A method of purifying an exhaust gas, includes: disposing a NOx trapping catalyst in an exhaust pipe of an internal combustion engine, the NOx trapping catalyst including: a metal substrate including cells, a corner portion of each of cells having an acute angle; and a catalyst layer supported in the metal substrate and including a noble metal, a heat-resistant inorganic oxide and a NOx trapping material, the catalyst layer having pores formed by addition of a pore formation promoting material, and the NOx trapping catalyst: adsorbing NOx in the exhaust gas when an exhaust air-fuel ratio is in a lean state; and desorbing and reducing the adsorbed NOx when the exhaust air-fuel ratio is in a stoichiometric state or a rich state; and removing the NOx by the exhaust air-fuel ratio being shifted between the lean state and the rich state.
Abstract:
In an image reading apparatus for reading an original image using a light source containing a plurality of color components, a control pulse for dimming the light source is generated by pulse-width modulation symmetrically with respect to a reference timing (for example, the central position in one storage time or the storage start timing) in one predetermined storage time of a line sensor.
Abstract:
An electronic equipment system includes an electronic device, a loading device for loading into and unloading from the electronic device, a light emitting section in the electronic device corresponding to the loading device, and an optical fiber corresponding to the loading device. The optical fiber transmits light from the light emitting section from a first end to a second end of the optical fiber.
Abstract:
A debugging support device includes: a plurality of CPU simulating units which simulates the operations of a plurality of CPUs which executes programs in parallel; a memory simulating unit of a memory to be shared by the plurality of CPUs; an event monitoring unit that detects a predetermined event occurring between each CPU simulating unit and the memory simulating unit; and a state judging unit that judges whether the state of the occurred predetermined event matches a predetermined condition and, if the predetermined condition is matched, records history information related to the state of the memory simulating unit.

Abstract:
A program parallelization supporting apparatus determines a determinacy in at least one dependency relationship of a data dependency, a control dependency and a pointer dependency in a program, extracts a critical path in the program, and extracts a processing instruction which exists on the critical path and has a non-deterministic determinacy in the dependency relationship. Furthermore, if a process related to a path of the extracted non-deterministic processing instruction is parallelized and the path of the non-deterministic processing instruction is deleted, the program parallelization supporting apparatus outputs parallelization labor hour information depending on the number of dependency relationships disturbing the parallelization and parallelization effect information depending on the number of processing instructions which are shortened by the parallelization.
Abstract:
By performing main fuel injection and sub fuel injection to perform rich operation of an engine, NOx purging of a NOx catalyst is carried out, and in the NOx purging, the ratio between the main fuel injection quantity and the sub fuel injection quantity is variably determined, within the range of 5:1 to 2:1 where the ratio of the sub fuel injection quantity is relatively great, such that the ratio of the sub fuel injection quantity is greater as the temperature of a three-way catalyst becomes higher.
